Status changed to 'Confirmed' because the bug affects multiple users.

The bug is that the linux-container.postinst script tries to update /etc/inittab on Ubuntu, which doesn't exist. The postinst needs to be setting up the proper /etc/init/linux-container.conf (i.e., upstart script) instead.

[Al Stone (ahs3)]

Workaround to let the package install (but likely not operate correctly) is to:

   $ sudo touch /etc/inittab
   $ apt-get install linux-container
